Car Air Conditioner Service
Cranbourne Auto Electrical and Mechanical have the skills to perform all of your Automotive Air Conditioner inspections, repairs and servicing in Cranbourne and the surrounding areas.
These days cars are often complex and just like the engine, a vehicles air conditioning system has elements that need to be serviced or replaced on a regular basis.
Don’t Melt In Your Car
Send the heat packing. Automotive air conditioning uses refrigerant to extract the heat from the air within the inside of the car then move it to the exterior, leaving only cooled or 'conditioned' air to be redistributed. It is very important to examine the condition of the rubber seals for any signs of leaks or damage which could be a sign of a loss of refrigerant.
When this refrigerant has started to leak or evaporate your air con system will begin to deteriorate and have to work harder meaning you are using even more fuel. Even new cars can lose as much as 20% of their refrigerant gas in the first two years.
To run most efficiently it is strongly recommended that the refrigerant in your Car Air Conditioner system is replenished completely within four years of the manufacture date and every two to three years after that.
Having your car's air conditioning serviced every twelve months means you can help prevent costly breakdowns now and in the future - and a well serviced Car Air Conditioner actually saves you money because it reduces the amount of fuel being burned.
Your vehicle should be taken to a qualified workshop such as Cranbourne Auto Electrical (AU25115) regularly to make sure the air conditioning system continues performing as it should as well as having the mechanics go over the condition of the whole vehicle.
Repco Authorised Car Service mechanics perform a 65 Point Vehicle Inspection Report with every service and are usually able to provide a warning about any components that may need to be renewed in the near future or those that are already worn beyond repair.
Cranbourne Auto Electrical in Cranbourne are qualified to take charge of air conditioning repairs, services and regas on most makes and models (AU25115).
Air Conditioning FAQ's
A car air conditioning system contains four basic parts - a pump, driven by a belt and known as a compressor (to compress and ciculate refrigerant gas), a radiator like unit called a condenser to release heat and condense gas to a liquid, the evaporator (a type of heat exchanger) to extract heat from the car and dehumidify refrigerant and an expansion device which could be a thermal expansion valve (TXV) or an orifice tube, (depending on the type of air-con system used).
A vehicle air conditioning is designed to extract the excess heat from the air in the car then move it to the outside, leaving only cooled or 'conditioned' air to be recirculated. As hot air is passed across the fins of the evaporator the heat is easily absorbed by the refrigerant (in gas form), effectively removing the heat from the air in the car and taking it outside.
The now heated gas is pulled through the compressor where it is further heated (via compression) to a very high temperature. The refrigerant is then literally forced through the condenser, allowing the cooler outside air to quickly extract the heat from the refrigerant as it is condensed to a liquid. The refrigerant then moves through the expansion device (either a TXV or Orifice tube), which regulates the flow of refrigerant going to the evaporator. At this point the refrigerant expands back into a gas form and the entire process begins again.
What is involved in a car air conditioning service?
A typical air conditioner service may include
Air vent temperature assessment
- Condenser temperature evaluation
- Check suction line temperature
- Adjustments of pulley and drive belt
- Check operation of thermostats and valves
- Ensure cleanliness of the condenser fins
- Ensure good condition of of components and hoses
- Evacuation and recharge of refrigerant (where required)
- System line and component inspection with electronic tester
Why do I need a car air conditioner system service?
Avoiding compressor seizure is achieved by checking or changing the oil level in the refrigerant. Should the air filters get choked with dirt and bacteria it will affect the performance of the entire system and it can even cause it to quit functioning altogether. As well as degrading air conditioner performance, dirty air filters can cause all kinds of health problems too.
Your car air conditioner system needs to be examined annually for any signs of failure of the hoses, connections and seals and ensure the refrigerant has not leaked over time. Regularly servicing your automotive air conditioning system keeps refrigerant at optimum levels meaning the system does not need to work as hard and this in turn protects the system from damage and results in a reduction of fuel consumed.
A vehicle air conditioning unit is designed to extract the excess heat from the air in the car and send it to the outside, leaving only cooled or 'conditioned' air to be recirculated. This is achieved using a special compound called refrigerant, capable of readily absorbing heat as a gas and quickly losing heat as a liquid.
Although it operates in a way like a domestic refrigerator, there are still a number of crucial differences. Seeing as it is mounted on your car, the air conditioner is subjected to a large amount of movement and vibration, in addition to having to function in an outdoor environment.
Being exposed to the elements and very stressful operating temperatures and being expected to run occasionally rather than being 'Always On' can cause breakdown of the connections, hoses and seals. An air conditioner ought to be inspected annually while being serviced every two years to ensure there are no problems or refrigerant loss due to failure or leakage from these points.
Simply by cooling the air in your car under normal running conditions, the filters of the air con get dirty. If the system is run infrequently, seals may dry and crack allowing them to leak and the air conditioning system can lose as much as 15% of its refrigerant in a single year. Even without leaks, the gas in a car air conditioning system will eventually degrade or evaporate over time and should be recharged regularly to keep the air con system in peak running condition
Under Australian law, only qualified mechanics with the appropriate licences are able to service or repair car air conditioning systems, especially where regas (recharging of the refrigerant) is concerned. Strict guidelines and procedures must be adhered to when handling refrigerant, which must always be fully recovered and not allowed to escape into the atmosphere during servicing.
Refrigerant can also pose serious health risks if handled incorrectly. Specialist equipment is also required as the air conditioning system is under extreme pressure and must be pulled into a deep vacuum to remove any moisture, which can seriously damage the system.You can find out more about licensing on the Australian Refrigeration Council (ARC) Website.
The moist environment can promote the development of bacteria, microbes and even fungus growth inside the evaporator core. This can lead to nasty smells and possibly even be bad for the health of any vehicle occupants. Newer type evaporator units tend to be more efficient, yet have increased capability to trap moisture and allow for micro-organism development.
Cranbourne Auto Electrical mechanics employ specialised ultrasonic technology to ensure the eradication of any micro-organisms possibly causing any bad smells or health issues.Just ask about our MIST service, which will kill any bacteria that may be lurking in your Car’s Air system. These bacteria can cause odours and even make you sick, especially if you have allergies or asthma. A MIST service doesn’t just make your car smell better - it makes it healthier for you and your family.
